Designed and manufactured in Rome, NEO jewelry is made of neoprene, a particular type of rubber normally used for wet suits in diving or in the car and plumbing industry. It is velvety, flexible and soft to the touch. Each piece is made by hand using traditional techniques such as knitting crochet and macrame. This lightweight choker features net like twisted nylon thread that holds dozens of grey foam rectangles. An easy snap for putting on and taking off.
